Rock salt refers to the dry salt extracted from saliferous rock layers with the help of mining methods.There are two main methods of extracting salt in underground mining: cut and blast mining and continuous mining.
According to the method for extracting the lithium from the aluminious rock, and the diluted acid is used as an extracting agent, the impurities in the extract are removed to obtain a high-purity lithium salt. The method has the advantages of low energy consumption and low extraction cost. ...
